The same as the size adjustment of the upper pallet 1, so that the present invention can be adjusted according to the size of different goods. In the present invention, the structures of the upper extension module 3 and the lower extension module 4 may be the same or different. In the following embodiments, the upper extension module 3 and the lower extension module 4 adopt the same structural design to explain the present invention. .

The upper pallet 1 is composed of at least two upper main beams and at least two upper auxiliary beams 14. As shown in Figures 1 and 2, multiple upper main beams and upper auxiliary beams can be provided. The upper auxiliary beams 14 are arranged in a normal direction, and they are perpendicular to each other on the horizontal plane. When two upper main beams and two upper auxiliary beams are provided, the upper main beams and the upper auxiliary beams 14 form a tic-shaped shape. An upper airbag 11 is provided at the bottom of the connection between the upper main beam and the upper auxiliary beam 14. The upper extension module 3 is provided on the upper main beam. The upper extension module 3 divides the upper main beam into The first upper main beam 12 and the second upper main beam 13 . The end of the first upper main beam 12 connected to the upper extension module 3 and the end of the second upper main beam 13 connected to the upper extension module 3 are the inner ends, and the end away from the upper extension module 3 is the outer end.

As shown in Figures 1 and 3, the number of lower main beams is consistent with the number of upper main beams, and their positions correspond to each other. , the number of lower sub-beams is consistent with the number of upper sub-beams, and their positions correspond to each other. The lower main beam and the lower sub-beam 24 are arranged in a normal direction, and they are perpendicular to each other on the horizontal plane. In the case of two lower main beams and two lower sub-beams, the lower main beam and the lower sub-beam are The lower sub-beam 24 forms a tic-shaped shape, and a lower airbag 21 is provided at the top of the connection between the lower main beam and the lower sub-beam 24. The upper airbag 11 abuts on the lower airbag 21. The cargo of the present invention It is placed on the upper tray 1, and the shock absorption effect is achieved through the upper air bag 11 and the lower air bag 21, which is consistent with the technical solution described in the patent number 201620978801.X. The lower extension module 4 is provided on the lower main beam. The lower extension module 4 divides the lower main beam into a first lower main beam 22 and a second lower main beam 23. The first lower main beam 22 and The end connected to the lower extension module 4 and the end connected to the second lower main beam 23 and the lower extension module 4 are the inner ends, and the end far away from the lower extension module 4 is the outer end. The end of the lower sub-beam 24 extending to the outside of the lower main beam is provided with a two-way limiting column 25. As shown in Figures 1 and 3, the end of the lower main beam extending to the outside of the lower sub-beam 24 (i.e. the first The outer end of the lower main beam 22 and the outer end of the second lower main beam 23 are provided with horizontal limiting columns 26, as shown in Figures 1 and 3. The horizontal limiting columns 26 are used to extend from the upper main beam to the upper auxiliary beam. The outer ends of the beam 14 (that is, the outer end of the first upper main beam 12 and the outer end of the second upper main beam 13) are limited, and the two-way limiting column 25 is used to limit the extension of the upper sub-beam 14 to the upper main beam. The outer end is limited, and the horizontal limiting column 26 and the two-way limiting column 25 can limit the position of the upper pallet 1 in the horizontal direction. The top of the two-way limiting column 25 is also provided with a stop extending in the direction of the upper main beam, thereby limiting the upper pallet 1 in the vertical direction and preventing the upper pallet 1 from coming out of the lower pallet 2 . The shape, size, and structure of the lower extension module 4 and the upper extension module 3 are the same. The shape, size, and structure of the first lower main beam 22 are the same as the shape, size, and structure of the first upper main beam 12. The second lower main beam 23 has the same shape, size and structure as the first lower main beam 22 .

The bottom surface of the upper main beam is provided with at least two limiting supports 15 . The two limiting supports 15 are symmetrically arranged on both sides of the upper extension module 3 . The limiting supports 15 can be on the upper air bag 11 When the lower airbag 21 suddenly fails, it will contact the top surface of the lower main beam and play a role in supporting the upper pallet 1 . At the same time, when the present invention is not used, the two airbags can be deflated, the limiting support 15 is abutted on the lower main beam, and the upper pallet 1 is supported through the limiting support 15 to prevent the two airbags from being compressed. bad. After the upper airbag 11 and the lower airbag 21 are inflated, the limiting support 15 is separated from the lower main beam.

At least two cargo fixing ends 16 are provided on the outer wall of the upper main beam, and the two cargo fixing ends 16 are symmetrically arranged on both sides of the upper extension module 3 . The cargo fixing end 16 can be used to wrap a tie for binding cargo.

In order to further optimize the upper extension module 3 and the lower extension module 4, improve the convenience of installation of the upper extension module 3, and achieve the effect of rapid size adjustment, we provide the following implementation as the first implementation of the upper extension module 3 Method (the structure of the lower extension module 4 is the same as that of the upper extension module 3. Here, the upper extension module 3 is used as an example. The structure of the first lower main beam 22 is the same as that of the first upper main beam 12. The structure of the second lower main beam 23 is the same as that of the upper extension module 3. The structure is the same as that of the second upper main beam 13, which will not be described in subsequent embodiments). The upper extension module 3 is a first extension module 5, and the first extension module 5 is plate-shaped. The two ends of the module 5 are respectively a first connection end 51 and a second connection end 52. The first connection end 51 is movably connected to the end of the first upper main beam 12, and the second connection end 52 is connected to the end of the first upper main beam 12. The ends of the second upper main beam 13 are movably connected, and a chute 53 is provided on the end surface of the first connecting end 51. The chute 53 is a long open groove and runs through the front and rear sides of the first connecting end 51. As shown in Figure 4, the cross-section of the chute 53 is tapered with a gradually decreasing opening size. The inner wall of the chute 53 is arc-shaped. The opening of the chute 53 is provided with a clamp extending toward the inside of the chute 53. The second connecting end 52 is provided with a slider 54. The slider 54 has a tapered cross-section that is adapted to the cross-section of the slider 53. The difference is that there is a clearance fit between the slider 54 and the slider 53. The end of the bar 54 is not arc-shaped, so that there is a certain degree of freedom between the two, and the side of the slide bar 54 close to the clamping table is provided with an movable groove, between the two adjacent first extension modules 5 The first connecting end 51 is movably connected to the second connecting end 52. A first limiting member 55 is provided in the chute 53. The first limiting member 55 is an elastic member, and the first limiting member 55 is located on the slider. In the movable groove of 54, the first limiter 55 is located between the clamping table and the slider 54. By providing the first limiter 55, the connection between the slider 54 and the slider 53 can be made closer, thereby increasing the firmness of the connection. At the same time, when vibration occurs, the upper extension module 3 can also have a certain degree of freedom, thereby increasing its service life. The way the slide bar 54 and the chute 53 are slid and connected makes the operation faster during assembly. In order to further optimize the structural design, the end of the first upper main beam 12 has the same shape as the second connecting end 52 , and the end of the second upper main beam 13 has the same shape as the first connecting end 51 same. Therefore, when the first extension module 5 is not needed, the first upper main beam 12 and the second upper main beam 13 can be directly spliced together to further reduce the size of the present invention. When the volume of the present invention needs to be increased, multiple first extension modules 5 only need to be provided.

In the first embodiment, the connection between the first extension module 5 and the first upper main beam 12 and the second upper main beam 13 is achieved by sliding on the side. However, in practical applications, the sliding method is horizontal. The first extension module 5 cannot be limited in the direction. When the transportation cycle is long, the first extension module 5 has the risk of slipping from the side, so we provide a second implementation method in order to facilitate size adjustment. to achieve all-round limitation of the upper extension module 3. In the second embodiment, the upper extension module 3 is a second extension module 6, and the second extension module 6 is cross-shaped. As shown in Figure 5, the first upper main beam 12 and the third upper main beam 12 are in the shape of a cross. The inner ends of the two upper main beams 13 are hollow connecting pipes, and the connecting pipes of the first upper main beam 12 and the second upper main beam 13 are provided with at least three through holes, and the through holes can be provided on The side wall of the connecting pipe can also be arranged on the top of the connecting pipe. In this embodiment, we take the arrangement on the top as an example. The two ends of the second extension module 6 are respectively symmetrically arranged third connecting ends 61 and a fourth connecting end. The third connecting end 61 is located in the connecting pipe of the first upper main beam 12 . The third connecting end 61 is provided with at least three second limiting members 62 . The member 62 is arranged on the upper part of the cross-shaped second extension module 6. As shown in Figure 6, by providing a plurality of second limiting members 62, the top of the third connecting end 61 is divided into a plurality of first limiting grooves 63. , the second limiting member 62 and the cross-shaped second extension module 6 form a first limiting groove 63, the shape and position of the first limiting groove 63 are adapted to the through hole, and the through hole A third limiting member 64 extending into the first limiting groove 63 is provided in the hole. The shape of the third limiting member 64 is adapted to the shape of the through hole. As shown in Figure 6, the third limiting member 64 64 is a cube, and the top of the third limiter 64 is provided with a buckle. When adjusting the size of the present invention, adjust the position of the third connecting end 61 in the connecting pipe, and ensure that there is at least one through hole connected with the first limiter. The grooves 64 are opposite to each other. After adjustment, insert the third limiting member 64 into the first limiting groove 64 through the through hole. When the third limiting member 64 is completely inserted into the first limiting groove 64, it is necessary to ensure that the third limiting member 64 is fully inserted into the first limiting groove 64. The top surface of the third limiting member 64 is flush with the top surface of the first upper main beam 12, and the position of the third limiting member 64 is defined in the horizontal direction through the through hole, and because the top surface of the third limiting member 64 is aligned with the top surface of the first upper main beam 12, The first upper main beam 12 is flush, so the cargo will be completely pressed against the top surface of the third limiting member 64, thereby limiting its position in the vertical direction. The fourth connecting end is located in the connecting tube of the second upper main beam 13. The shape and size of the fourth connecting end and the second upper main beam 13 are the same as those of the third connecting end 61 and the second upper main beam 13. The first upper main beam 12 is the same.

In the second embodiment, an axial sliding insertion method is adopted to solve the problem of position limitation existing in the first embodiment. Although the structure of the second embodiment is compared with the first embodiment, It is more complicated, but the accuracy of size adjustment in the second implementation is higher than that in the first implementation (the first implementation can only increase or decrease a fixed length). Without considering the adjustment accuracy, we provide the second implementation. Three implementations to solve the problem of lateral position definition. In the third embodiment, the upper extension module 3 is a third extension module 7. The third extension module 7 is plate-shaped. The two ends of the third extension module 7 are respectively the fifth connection end 71 and the fifth extension module 7. The sixth connecting end 72, the fifth connecting end 71 is movably connected to the end of the first upper main beam 12, the sixth connecting end 72 is movably connected to the end of the second upper main beam 13, The fifth connecting end 71 is provided with a first connecting plate 711. The thickness of the first connecting plate 711 is half of the thickness of the fifth connecting end 71, and the first connecting plate 711 is located below the fifth connecting end 71. The first connecting plate 711 is The six connecting ends 72 are provided with a second connecting plate 721. The thickness of the second connecting plate 721 is half of the thickness of the sixth connecting end 72, and the second connecting plate 721 is located above the sixth connecting end 72. The first connecting plate 721 is The positions of 711 and the second connecting plate 721 are vertically symmetrical, as shown in Figures 7 and 8 . The top of the fifth connecting end 71 is provided with a second limiting groove 712 extending to the first connecting plate 711. The second connecting plate 721 is provided with a fourth limiting member 722, and passes through the third limiting groove 712. The four limiting members 722 are engaged with the second limiting groove 712. The engaging point between the second limiting groove 712 and the fourth limiting member 722 is arc-shaped, and the fourth limiting member 722 is an arc-shaped hook. , the end surface of the fifth connecting end 71 located above the first connecting plate 711 is a concave arc-shaped end surface, and the end surface of the second connecting plate 721 is in a shape suitable for the concave arc-shaped end surface of the fifth connecting end 71 . Easy to install. Taking the assembly of two adjacent third extension modules 7 as an example, during installation, as shown in A in Figure 9 , just snap the fourth limiter 722 and the second limiter slot 712 into place. After installation, , as shown in B in FIG. 9 , at this time, the fourth limiting member 722 is engaged with the second limiting groove 712 , and at the same time, the end surface of the second connecting plate 721 is engaged with the fifth connecting end 71 and is located above the first connecting plate 711 inside the concave arc-shaped end surface. When disassembling, just lift the second connecting plate 721 upwards. In this embodiment, the cooperation between the fourth limiting member 722 and the second limiting groove 712, and the cooperation between the second connecting plate 721 and the end surface of the fifth connecting end 71 jointly complete the position limitation in the horizontal direction, because the goods are It is placed above the third extension module 7, so the cargo will limit it in the vertical direction to prevent the fourth limiting member 722 from being detached from the second limiting groove 712. Similar to the first embodiment, in order to further compress the volume of the present invention, the end shape of the first upper main beam 12 is the same as the sixth connecting end 72 , and the end shape of the second upper main beam 13 is the same as that of the sixth connecting end 72 . The fifth connecting ends 71 are the same, so that when the third extension module 7 is not provided, the first upper main beam 12 can be connected to the second upper main beam 13 .

The above three embodiments can basically meet most road conditions. However, for transportation sections with many potholes, there is a risk of cargo sliding. Because the present invention has a split structure design, once the vehicle passes through the potholes, More generally, as the vehicle body swings, the upper extension module 3 is easily damaged by force in the horizontal direction. Therefore, in order to further enhance the firmness of the connection of the upper extension module 3, we provide a fourth implementation method. In this embodiment, the upper extension module 3 is a fourth extension module 8. The fourth extension module 8 is plate-shaped. Both ends of the fourth extension module 8 are symmetrically provided with seventh connection ends 81 and a third extension module 8. The thickness of the eighth connection end 82 and the connection between the seventh connection end 81 and the fourth extension module 8 is half of the thickness of the fourth extension module 8 . The thickness of the end of the seventh connection end 81 away from the fourth extension module 8 is smaller than the thickness between the end and the fourth extension module 8 .
